Hit and miss on recording movement on Model # VMB3000

[MelodyC]

Any ideas on how to get the system to consistantly record upon movement?  We've had three cameras replaced, and still it is hit and miss during the day on recording.  Also, it's not recording at night.    For instance yesterday on our gate camera:  Husband drove up - recorded.  I drove up about 15 min later - no recording.   We drove out - recorded.  It caught the neighbor (thank goodness!) coming up to our house and snooping around, and us returning.  

I switched modes to our night camera set up (all set at 95% & record video), and nothing.  It didn't even catch my husband leaving this morning.  

Any ideas would be appreciated!  I've checked, double checked, triple checked, and more the settings.   Sometimes it will record, but more often than not, it won't.

FWIW, I set nighttime recording to 100% - I want everything.

How is the motion relative to the camera? Motion is detected best across the field of view, not directly at it. Maybe screenshots would help.
